The problem being the typical lack of neutral - hence nowhere to put it!

That only applies to (some) retro-fits and, even then, routing in a
neutral is not impossible. Why isn't such an indicator light-switch
available for new builds where the electrician would know in advance
that a neutral is required? Is it so unusual to have the switch on the
outside of the understairs loo?
